It’s been a long road, but it looks as though SpaceX may finally be ready for an orbital flight test with the Starship and Super Heavy. After months of waiting, static fire tests, stacking, and restacking, Elon Musk announced on March 16th that SpaceX could be ready to go with the SN24 and BN7 prototypes in “a few weeks,” pending approval from the Federal Aviation Administration (FAA). Musk announced via Twitter, saying, “launch timing depends on FAA license approval. Assuming that takes a few weeks, first launch attempt will be near end of third week of April, aka…”

OK, LEGO fans, it’s time to vote this awesome new LEGO Idea into existence! A stunning new 2,360-piece Lego Art space poster called “The Moon: Earth’s Companion” is currently gathering supporters on the LEGO Ideas website. If it gets enough votes, LEGO will review it and possibly create it.

When it comes to the brightest, most powerful objects in the Universe, not much can beat a Quasar. A Gamma Ray Burst from a supernova might be more energetic, but doesn’t last very long. Quasars, by comparison, can churn out 1000 times the radiation of the Milky Way, and keep doing it for hundreds of millions of years.

Researchers have discovered that in the exotic conditions of the early universe, waves of gravity may have shaken space-time so hard that they spontaneously created radiation.

There’s an interesting problem in exoplanet studies: how to tell if a planet has a magnetosphere. It’s not like we can visibly see it unless we find a different way of looking. A pair of scientists may have found one. They used radio telescopes to track emissions given off by magnetic star-planet interactions. These happen when a planet with a magnetic field plows through star stuff caught its star’s magnetic field.

The James Webb Space Telescope has taken a stunning new image of the ice giant world Uranus. But what stands out most is the dramatic new view of the planet’s rings, which show up as never before with JWST’s infrared eyes.

The brightest gamma-ray burst ever seen in 2022 still puzzles astronomers.

A new map created with decades-old radar imagery from NASA’s 1990’s Magellan mission shows the locations of a whopping 85,000 volcanoes on Venus. The detailed map displays where the volcanoes are, how they’re clustered, and how their distributions compare with other geophysical properties of the planet such as crustal thickness.

The China National Space Agency (CNSA) has made considerable progress in recent years with the development of its Long March 5 (CZ-5) rocket and the completion of its Tiangong-3 space station. The agency also turned heads when it announced plans in June 2021 to create an International Lunar Research Station (ILRS) that would rival the Artemis Program. On top of all that, China upped the ante when it announced later that month that it also had plans to send crewed missions to Mars by 2033, concurrent with NASA’s plans.

One of the more intriguing aspects of the cosmos, which the James Webb Space Telescope (JWST) has allowed astronomers to explore, is the phenomenon known as gravitational lenses. As Einstein’s Theory of General Relativity describes, the curvature of spacetime is altered by the presence of massive objects and their gravity. This effect leads to objects in space (like galaxies or galaxy clusters) altering the path light travels from more distant objects (and amplifying it as well). By taking advantage of this with a technique known as Gravitational Lensing, astronomers can study distant objects in greater detail.

NASA’s Perseverance rover mission provided a blueish pre-sunrise gift above Jezero Crater on March 18, 2022, aka Sol 738, or the 738th Martian day of the mission, with “sol” being the official timekeeping method for Mars missions since one Martian day is approximately 40 minutes longer than one Earth day. The car-sized explorer used one of its navigation cameras (Navcam) to snap images of high-altitude clouds drifting in the Martian sky, which it shared on its officially Twitter page on March 23, 2023.

It probably comes as no surprise to people living in low-lying coastal regions, but sea waters are rising by large, measurable amounts. That assessment comes from NASA, which has analyzed 30 years of sea-level satellite measurements. The news is not good. Since 1993, the seas rose by a total of 9.1 centimeters. Two years ago, it went up by 0.27 centimeters.

In 1997, George Lucas released the special edition remaster of his Star Wars trilogy, making changes to the special effects that both delighted and divided fans worldwide (did Han shoot first?). Among the myriad additions was a visually spectacular ring-shaped shockwave emanating from the exploding Death Star, and Alderaan too. Star Trek fans will delightedly point out that this particular special effect had previously been used in the 1991 film Star Trek VI: The Undiscovered Country, in which the Klingon moon Praxis explodes, giving the effect its name: the Praxis ring. Hollywood lore suggests Lucas was so impressed with the effect in that film that he added it to Star Wars too.

The four astronauts chosen for NASA’s Artemis II mission will check off a string of firsts during their flight around the moon, scheduled for next year. It’ll mark the first trip beyond Earth orbit for a woman, for a person of color and for a Canadian. Artemis II will represent yet another first for Canadian astronaut Jeremy Hansen: Based on the current crew schedule, it’ll be his first-ever space mission.

In 1931, Indian-American physicist Subrahmanyan Chandrasekhar proposed a resolution to Einstein’s Theory of General Relativity that postulated the existence of black holes. By 1972, astronomers obtained the first conclusive evidence that these objects existed in our Universe. Observations of quasars and the center of the Milky Way also revealed that most massive galaxies have supermassive black holes (SMBHs) at their cores. Since then, the study of black holes has revealed that these objects vary in size and mass, ranging from micro black holes (MBHs) and intermediate black holes (IMBHs) to SMBHs.

Roscosmos has had quite the run of bad luck lately. In addition to sanctions putting pressure on their space program and the cancellation of agreements (all due to the war in Ukraine), the Russian space agency has experienced several problems in space. On December 14th, 2022, and February 11th, 2023, two space capsules reportedly suffered radiator coolant leaks (Soyuz MS-22 and Progress 82). In addition to delivering fresh supplies to the International Space Station (ISS), one of the spacecraft (M-22) was slated to bring three members of Expedition 68 back to Earth.

We finally got JWST data about TRAPPIST-1. An Earth-sized rogue planet was found. More information about China’s plans for the Moon.

In June 2021, China announced it was partnering with Russia to launch a lunar exploration program that would rival NASA’s Artemis Program. This program would include robotic landers, orbiters, and crewed missions that would culminate with the creation of an outpost around the Moon’s southern polar region – the International Lunar Research Station (ILRS). While the details are still scant, periodic updates have provided a “big-picture” idea of what this lunar outpost will look like.

In November 2024, NASA’s Artemis II mission will launch from Cape Canaveral, carrying a crew of four astronauts around the Moon before returning home. This will be the first crewed mission of the program, paving the way for Artemis III and the long-awaited return to the Moon in 2025. These missions will rely on the Orion spacecraft and the Space Launch System (SLS) super-heavy launch vehicle. At NASA’s Michoud Assembly Facility in New Orleans, teams of engineers have just finished integrating all five major structures that make up the core stage of the Artemis II rocket.

A couple times a year, the Hubble Space Telescope turns its powerful gaze on the giant planets in the outer Solar System, studying their cloudtops and weather systems. With the Outer Planet Atmospheres Legacy (OPAL) Program, Hubble provides us with these views and also delivers weather reports on what’s happening. Here’s an updated report and some new images of the stormy surfaces of Jupiter and Uranus.  

New in-space propulsion techniques seem to be popping out of the woodwork. The level of innovation behind moving things around in space is astounding, and now a company from Japan has just hit a significant milestone. Pale Blue, which I assumed was named as a nod to a beloved Carl Sagan book, recently successfully tested their in-orbit water-based propulsion system, adding yet another safe, affordable propulsion system to satellite designers’ repertoires.
